Starter fertilizer

Fundamentally you should only really need N or P via a starter. And even then if P reserves are decent then you should question that.

Anything that has to swing from the Manitou is going to be far better value than something that comes in a van. Do not get sucked into the high margin "starter" world or the microgranular world in my opinion.

Very often because my P sources come from FYM, unless the soil is short I'll use whatever N I have handy about - often Urea, sometimes AS or AN.

If it were solid, a nice soluble form would be DAP. 160 kg/ha gives you 30 kg of N and 74 kg of P (enough P for the entire crop).

I will be fitting a liquid kit to my next drill & it will use the same N+S liquid I use for foliar treatment for the only reason being simple logistics. I'd have a bit of P in it too if I had the spare tanks. I prefer to keep my soil P indices above 2 so the crop can get what it needs fairly quickly.

can you melt down DAP without it separating after mixing?
